“There will be 92 blocks offered in the offshore sedimentary basins of Potiguar, Campos, Santos and Pelotas,” the ANP said in a statement. The blocks cover 53,900 square kilometers of area, according to the ANP. The ANP will hold a public audience to discuss the auction rules and concession contract Feb. 3, with the public bidding round scheduled to be held Oct. 7.
The approval of the blocks followed a Dec. 11, 2020, CNPE decision to remove 32 offshore blocks from the sale because of environmental concerns, which have caused issues with drilling permits after recent sales. That included denials to drill in the Para-Maranhao and Foz do Amazonas basins along Brazil’s equatorial margin, which caused industry heavyweights such as BP Energy and Total to bail out of the promising area.The CNPE removed eight blocks in the Para-Maranhao Basin and 24 blocks in the Pelotas Basin from the 17th bid round in the December move.
Several of the blocks were expected to generate heated competition despite the environmental concerns, because of the potential for holding deepwater deposits similar to ExxonMobil’s Stabroek block discoveries off the coast of Guyana. The US heavyweight has made 18 discoveries and pumped first oil from the block in December 2019. The Stabroek block is estimated to hold more than 8 billion barrels of oil equivalent in recoverable reserves.The same play is believed to extend along Brazil’s northern coast in the Foz do Amazonas and Para-Maranhao basins, according to geologists.
Environmental groups, however, started to protest against drilling in the region after the discovery of a coral reef in the turbid waters at the mouth of the Amazon River. The groups said drilling could damage the reef and affect marine life in the area. The claims have gained even more weight during the coronavirus pandemic, which has made companies reevaluate environmental issues amid calls for greater reductions in greenhouse gas emissions to counter climate change.
The removals, however, also underscored that regulators were working more closely together to avoid the types of uncertainties that undermine investors. Since 2016, the ANP has worked with the Brazilian Institute of the Environment and Renewable Natural Resources (IBAMA) on preliminary approvals after winning bidders at the 11th and 12th bid rounds were prohibited from drilling in many of the blocks sold.
The 12th bid round featured 72 onshore blocks primarily earmarked for oil and natural gas exploration and production that utilized hydraulic fracturing techniques. A series of court-ordered injunctions blocked further development and resulted in blocks being returned to the ANP. The ANP has since worked to secure preliminary environmental reports with IBAMA ahead of the bid rounds to ensure no major issues will appear during the process to secure drilling permits.
The latest changes to the 17th bid round lineup also included the consolidation of six blocks in the ultra-deepwater portion of the Santos Basin down to two blocks, the ANP said. The S-M-1613 and S-M-1615 blocks will now be wrapped into the S-M-1613 block, while the S-M-1617, S-M-1619, S-M-1729 and S-M-1731 blocks were consolidated into the S-M-1617 block, the ANP said.
The consolidation will expand the size of the blocks available and potentially make them more attractive to potential investors, especially in frontier areas without a long history of exploration and production such as in the southern Santos Basin.
The 17th bid round will also be the first to include blocks beyond Brazil’s 200 nautical mile Exclusive Economic Zone, which was approved by the CNPE in February 2020. The blocks hold subsalt potential and are located on the southern fringe of the subsalt polygon that requires production-sharing contracts for development. The areas, however, will be sold under the more-favorable concession contract that requires oil companies to pay royalties on output rather than guarantee the government a share of profit-oil production.
Future auctions will likely include additional concession blocks that sit beyond 200 nautical miles of the coast as Brazil looks to delimit the full scope of the subsalt frontier, according to government officials.
